    I've recently installed a 2.33ghz c2d chip in my old 1.66 cd mac mini. The performance boost has been great!

    I've noticed temps have gotten a little high while running encodes and such... around low - mid 90s C while handbrake is encoding. I know this is still within operating temperature, but i'd like them to be a little lower.

    I managed to keep the plastic clips from breaking while installing my cpu. I've been thinking about replacing the nylon clips with some nylon screws, like others have mentioned.

    My question, Do people use the springs that came with the clips when installing the screws? Or do people just screw the heatsink down snug to the cpu without the springs?

    Suggest you install smcfancontrol and manually adjust your fans when encoding. Your mini's air flow was designed for the original processor. Works great on my 2010 mini and my Mac pro's I used to have.

    I do use smc fan control while i'm encoding. It does a pretty good job. Keeps the temps down around 80C while encoding with fan rpm around 3800.

    With the plastic clips, the springs were required to maintain pressure between the heatsink and the CPU. You don't need the springs if you're using screws and nuts. I used nylon screws and nylon lock nuts. I see temps a few degrees lower than yours while encoding. Remember not to use too much thermal paste.

    Would any OEM C2D chip work?

    the 2.33 c2d is the fastest cpu in that socket. this was the top of the line mini mod in 2007/8. the socket changed in 09 and the cpu has been glued/soldered in tight

    Thanks for the reply. Right now i've got the plastic clips and crappy thermal paste from best buy in the mac mini. It gets the job done, but I'm thinking about redoing the thermal paste with better stuff and adding nylon screws, that should help keep temps down... and add a little life to the already ancient mac mini.
